American lieauti Pleat, Inc.,13545 Excelsior Drive, Norwallr, Calif. 90650) Filed May 17, 1966, Ser.No. 550,790 14 Claims. (Cl. 16-814) ABSTRACT OF THE DISCLOSURE A draperyglide adapted to engage with a pair of laterally spaced, parallel railsof a transverse rod and with the upper hem portion of a drapery arrangedbelow the transverse rod including, a unitary block-like body having asubstantially rectangular head portion greater in lateral extent thanthe free gap in the rod established by the rails and having a flatbottom surface to slidably engage the tops of the rails, said headportion being normally arranged with its major longitudinal axisparallel with the rails, a central neck portion depending from the headportion and projecting freely through and between the rails and a lowercarrier portion depending from the neck portion and greater inlongitudinal and lateral extent than the free gap, a first slot parallelwith the longitudinal axis of the structure entering the upper end ofthe body and terminating adjacent the lower end of the body to dividethe upper portion of the body into two laterally spaced, flexiblecolumns whereby the lateral extent of the head portion can be reduced toallow for engagement of the head portion through the free gap by lateralinward flexing of the column towards each other, a second slot on aplane normal to the plane of the first slot entering the lower end ofthe carrier portion and in which the hem portion of the drapery isarranged, intersecting the first slot and terminating adjacent the upperend of the said carrier portion to divide the lower portion of thecarrier portion and define a pair of longitudinally spaced, dependinglegs to engage the opposite side of the upper hem portion of thedrapery, and a unitary wire hanger pivotally carried by the body andhaving an elongate, longitudinally extending end portion normallyarranged in the first slot and engaged on the bottom of the first slotto bridge the second slot and project through the hem portion of thedrapery arranged in said second slot.

This invention has to do with a glide and is more particularly concernedwith a novel pop-in glide for use in connection with traverse roddrapery installations employing resillient, sinuate pleaters.

In the drapery art, it is common practice to provide an elongate,horizontally disposed traverse rod to support draperies. Traverse rodsare simple, elongate, rollformed sheet metal members, C-shaped incross-section to define a longitudinally extending slot or free gap anddefining a pair of straight, flat, longitudinally extending, parallel,laterally spaced rails or rail portions. Such rods are suitably mountedto extend longitudinally above and across a vertical planar area inwhich it is desired to suspend a drapery. The rods can be arranged withthe free gaps disposed laterally or downwardly as circumstances require.

The glide of the present invention is adapted to be related withtraverse rods which are arranged with their free gaps disposeddownwardly.

The draperies are ordinarily vertical, rectangular fabric panels and areprovided with supporting hems along their upper edges to occur adjacentthe rod. The upper hems are ordinarily gathered or pleated, or areprovided with pleater means.

The upper hem portions of the draperies are secured to the rods by meansof a plurality of longitudinally spaced glides, which glides havinglower drapery carrier portions; upper head portions which occur withinthe rods to bridge the free gap and slidably ride on the rails; and neckportions between the carrier and head portions and which project freelythrough the free gaps of the rods.

With the above general set up, it will be apparent that the draperypanels are suitably supported and are supported in such a manner thatthey can be shifted laterally, or horizontally, relative to the rods, ascircumstances require.

Resilient, sinuate, pleaters established of flat ribbon spring stockengageable in the upper hems of drapery panels are in wide use in thedrapery industry. These pleaters are provided with fastener-receivingopenings in those portions of the pleaters which extend across or occuron the means longitudinal axis of the pleaters and through whichsuitable fastening pins, hooks, and the like are engaged to secure theglides to the draperies.

The above-noted drapery construction presents a nurnher of special andunique problems not overcome with standard or conventional hardware andhas resulted in the establishment of numerous special and unique glidesand means for securing the glides to the drapery and pleater assemblies.

An object of my invention is to provide a novel glide construction fordraperies with sinuate spring pleaters having novel drapery and pleaterengaging means.

In the drapery art where sinuate spring pleaters are employed, it is orwould be desirable and advantageous to initially apply the glides to thedrapery and then or subsequently, with the draperies related thereto,engage the glides with their related rods. Unfortunately, the ordinaryglides are such that they must be assembled with the rods, by slidingthe glides into engagement with the rods at an open end of the rod. Suchassembly must ordinarily be performed before the rods are mounted. Thisrequirement prevents or makes impractical. relating the glides to thedraperies first and to the rods second.

An object of this invention is to provide a glide of the characterreferred to which is such that it can be shifted laterally intoengagement in and through the free gap of a drapery rod and need not beengaged with the rod from an open or free end thereof; whereby theglides can be advantageously applied to the draperies before beingassembled or related to the rods.

The above and other objects and features of my invention will be fullyunderstood from the following detailed description of a typicalpreferred form and application of my invention, throughout whichdescription reference is made to the accompanying drawings, in which:

FIG. 1 is an isometric view of a portion of a drapery installationemploying my new glides;

FIG. 2 is an enlarged side view of my new glides, taken as indicated byline 22 on FIG. 1;

FIG. 3 is an end view taken as indicated by line 3--3 on FIG. 2, withcertain parts removed;

FIG. 4 is a top View taken as indicated by line 4-4 on FIG. 3;

FIG. 5 is a view similar to FIG. 3 showing the other end of my glide;

FIG. 6 is a bottom view taken as indicated by line 6--6 on FIG. 5; and

FIG. 7 is a view showing the glide partially engaged with a traverserod.

The glide construtcion A that I provide is a two-piece assemblyinvolving a body B and a hanger H. The body B is a plastic partestablished of delron or nylon and is such, that it can beadvantageously injection molded. The

hanger H is a metal wire part which is such that it can be easily andconveniently formed by a suitable bending operation and which is suchthat it can be advantageously related to the body.

The body B of my glide A includes an upper head portion C, a lowerdrapery carrier portion D and a central or intermediate neck portion E.

The upper head portion C of the body B is a substantially flat,horizontal, rectangular portion having straight, parallel sides 10,rounded ends 11, upwardly disposed top surface 12, and a flat,downwardly disposed bottom or bearing surface 13. The straight, parallelsides and the ends 11 of the head portion C are radiused and/or inclinedto extend laterally inwardly and upwardly.

The head portion C is greater in longitudinal and in lateral extent thanthe free gap G of the traverse rod R with which the glide is to berelated and is such that when the glide is engaged with the rod R, thehead portion occurs within the rod and the bottom or bearing surface 13thereof slidably engages the upper or top bearing surfaces of theparallel rail portions R of the rod which portions establish the freegap G.

The lower drapery carrier portion D of the body B of my new glide A is arectangular block-like portion corresponding in lateral extent with thehead portion C, but slightly less in longitudinal extent than the headportion C. The carrier portion D is of substantial vertical extenthaving a flat, top surface 14 spaced below and opposing the bearingsurface 13 of the head portion C and a substantially flat, bottom end15. The top surface 14 of the carrier portion D is adapted to occurbelow and to oppose the lower sides of the rail portions R of thetraverse rod R and to prevent upward shifting and displacement of theglide A in or relative to the rod.

The carrier portion D is shown as having a flat, vertical ends 16 andvertical sides 17. In practice, to reduce the amount of material toestablish the body of my glide and to impart desired resiliency to thebody, as will hereinafter be described, the lower portions of the sides17 of the carrier portion D are relieved as indicated at 17.

The lower portion of the glide body A is bifurcated or slotted as at 18.The slot 18 enters the lower end of the portion D and occurs on a planeextending transverse the longitudinal axis of the glide, that is, fromone side to the other side of the glide. The slot 18 serves to define apair of substantially flat, transversely extending, longitudinallyspaced, depending legs at the lower portion of the body and betweenwhich the upper hem portion F of a drapery panel I, with a sinuatespring pleater J arranged therein,

can be arranged, as clearly illustrated in FIGS. 1 and 2 r of thedrawings.

In the upper portion of the carrier portion D, above the slot 18, Iprovide a transversely extending bearing opening 21 to receive a portionof the hanger H, as will hereinafter be described.

The slot 18 is of suflicient vertical extent and is of suflicientlongitudinal extent to freely accommodate the pleater I with the fabricof the drapery panel I engaged about said pleater.

The neck portion E of the body B is a vertically extending cylindricalportion formed integrally with and extending between the bottom surface13 of the head portion C and the top surface 14 of the carrier portionD.

The neck portion E is slightly less in diametric extent than the lateralextent of the free gap G of the rod R and is slightly greater invertical extent than the gauge or thickness of the stock from which therod G is established- In practice, the neck portion E, depending fromthe lower bearing surface 13 of the head portion C, extends freelythrough the free gap G of the rod -R and permits for free rotation ofthe glide, relative to the rod, on its vertical axis.

In addition to the foregoing, the head portion C, neck portion E and thelower hanger portion H of the glide body B is bifurcated or is providedwith a vertical slot 4 30, which slot enters the top end 12 of the bodyand terminates in the lower portion of the carrier portion D, a shortdistance above the bottom end 15 of the body.

The slot 30 occurs at right angles to the slot 18 in the carrier portionD and on the normal longitudinal axis of the body. The slot 30 is ofsubstantially vertical extent and intersects the slot 18, as clearlyillustrated in the drawings.

The slot 30 in the body B serves to divide the body into what may betermed as longitudinally spaced, vertically, upwardly projectingcolumns, the lower ends of which are bifurcated by the slot 18 enteringthe bottom of the lower portion D.

The slot 30 terminates in the lower portion of the carrier portion D ata flat bottom 32. It will be apparent that the bottom 32 is separatedinto two longitudinally spaced portions by the slot 18 entering thelower end of the body.

The slot 30 is such that it permits for lateral inward flexing andshifting of the columns of the body towards each other. In practice,such flexing and shifting can be such that the lateral extent of thehead portion C of the glide body is substantially equal to the lateralextent of the free gap G in the traverse rod, when the columns areflexed laterally inwardly towards each other and so that the upper endof the slot 30 is closed.

With such a relationship, it will be apparent that the head portion ofthe glide can be engaged through the free gap G of the rod R by simplyurging and pushing the head portion, with the plane of the slot 30extending parallel with the free gap, upwardly through said free gap.

It will be apparent that when the head portion C is arranged adjacentthe free gap G in the rod R, with the slot 30 parallel with the free gapand with the upper portions of the upwardly and inwardly inclined sides10 of the head portion engaging the opposing edges of the rail portionsR of the rod R, upon upward urging of the glide relative to the rod R,the inclined sides 10, acting as inclined planes, or cams, flex thecolumns and the divided sections of the head portion C laterallyinwardly towards each other and so that the head portion 10 is reducedsufliciently in lateral extent to pass through the free gap. As soon asthe head portion passes through the free gap, the slot 30 opens and theside edge portions of the head portion shift outwardly and so that thebottom surface 13 of the head portion, as noted above, establish slidingbearing engagement on the top surfaces of the rail portions R of therod.

In practice, the vertical extent of the head portion C can besufliciently thin so that when the glide is urged upwardly intoengagement with a rod R, in the manner set forth above, the sideportions of the head portion will or can flex downwardly a limitedextent.

By providing for such limited downward flexing of the side portions ofthe head portion C, the head portion can be made slightly greater inlateral extent than the free gap and the glide, when urged intoengagement with the rod, must be snapped or popped into engagement withthe rod.

Still further, and in order to provide the head portion C with maximumpossible lateral extent and to maintain the slot 30 of minimum lateralextent so as to leave the body with as much stock and strength as ispossible, the slot 30 can be made substantially equal in lateral extentwith the distance that one side portion of the head portion projectslaterally outwardly from the neck portion E.

With such a relationship, when it is desired to engage the glide with arelated traverse rod, the glide is arranged below the free gap G in therod R with the slot 30 thereof parallel with the free gap. The glide isthen tipped laterally so that one side edge of the head portion C of theglide projects through the free gap and establishes hooked engagementover its related rail portion R of the rod, as clearly illustrated inFIG. 7 of the drawings. The glide is then manually urged towards saidrelated rail portion of the rod so as to flex the columns of the glidebody towards each other and is simultaneously pivoted back towards theother or opposite rail portion of the rod, which pressure and pivotingcauses the other side portion of the head portion C to shift upwardlythrough the free gap and by its related rail portion of the rod.

In this case, as in the previous case, the side edge portions of thehead portion C can be slightly over gauged, laterally, so that the lastedge portion to be engaged with the rod, when it is urged through thefree gap G of the rod, must flex slightly.

In practice, and as illustrated in the drawings, the side walls of thegroove 30 can be radiused at their upper e i S, Where they join top 12of the head portion C, to relieve the body in such a manner that thecolumns 31 can be flexed a greater distance than would be possible ifthe sides of the groove were straight and uninterrupted throughout theirlongitudinal extent. Such radiusing of the sides of the groove 30 andrelieving of the construction does not weaken or adversely aifect thestructure.

It will be apparent that when my glide is engaged with the traverse rodR, it can be pivoted about its vertical axis and relative to the rod toany desired position without dropping or shifting out of engagement withthe rod, and is such that it will and can support considerable weight.

The hanger H that I provide is a simple, unitary bent wire part havingan upper U-shaped portion X and a lower hook portion Y. The upperU-shaped portion X has a horizontal primary leg 40 pivotally engaged inthe bearing opening 21 in the carrier portion D of the body and bridgingthe slot 30 therein. A downwardly and laterally projecting base 41 atone end of the primary leg 40 and a laterally inwardly turned,horizontal secondary leg 42, parallel with the primary leg portion 40,projecting laterally inwardly at one end of the body and terminating atthe central longitudinal, vertical plane of the body.

The hook portion Y of the hanger H is a longitudinally extending portionand includes a substantially straight downwardly and laterally inwardlyprojecting primaly arm portion 43 extending from the inner end of theleg 42 of the laterally extending U-shaped portion of the hanger whicharm portion 43 projects laterally inwardly and downwardly through theslot 30 in the body and terminates within the slot 18 in the body, belowthe bottom 32 of the slot 30. The hook portion Y further includes asecond-ary arm portion 44 extending or continuing from the lower innerend of the arm portion 43 and projecting laterally outwardly andupwardly from within the slot 18 and into the slot 30. The outer freeend of the arm portion 44 is sharpened as at 45 to facilitate the hookportion piercing the fabric of a drapery.

It will be apparent that the lower portion of the slot 30 is dividedlongitudinally into two end portions by the slot 18 entering the lowerend of the body and the primary arm portion 43 of the hanger H extendsthrough one lower end portion of the slot 39 and that the secondary armportion of the hanger H projects into the other lower end portion of theslot 30.

The lower inner end portions of the primary and secondary arm portions4-3 and 44 of the hook portion Y of the hanger H bear against and aresupported by the corners established by the walls of the slot 18 and theadjacent portions of the bottom 32 of the slot 30.

With the above relationship of parts, it will be apparent that thecentral upwardly opening bend d6 of the hook portion Y of the hanger H,established by the primary and secondary arm portions 43 and t4 normallyoccurs within the slot 18 and below the bottom 32 of the slot 30.Accordingly, in order to shift the hook portion Y, about the axis of theupper primary leg 41] of the upper portion X, and to shift the secondaryarm 44 of the hook portion Y out of engagement in the spot 1-8, thehanger H must be sprung slightly so as to cause the central upwardlyopening bend 46 to ride upwardly and over the ad jacent portion of thebottom 32 of the slot 30.

With the above relationship of parts it will be apparent that the hangerH is, in effect, spring loaded and is yieldingly maintained in itsnormal position, as illustrated in full lines throughout the drawings,and is such that it can be snapped out of said normal position to anopen position, such as is illustrated in phantom lines in FIG. 2 of thedrawings.

In operation or practice and when it is desired to connect the glidewith the drapery I and pleater J, the hanger is shifted to its openposition. The glide is then shifted into engagement with the assembleddrapery and pleater so that the hem F and pleater J are arranged withinthe slot 18 and so that a pin receiving opening 50- in the pleateroccurs adjacent the bottom 32 of the slot 30. When the glide is thusarranged with the drapery and pleater assembly, the hanger is pivoted sothat the secondary arm portion 44 of the hook portion Y swings laterallyinwardly, piercing the fabric and projecting through the opening 50 inthe pleater. When the hanger is thus shifted and returned to its normalposition, it will be apparent that the drapery and pleater assembly ispositively hooked by the hanger and is supported against verticaldisplacement from within the groove 18 thereby.

It will be further apparent that the weight of the drapery and pleaterassembly carried 'by the hook portion Y of the hanger is not transmittedto and through the upper portion of the hanger, but rather, istransmitted directly onto the longitudinally spaced columns at thebottoms 32 of the slot 30.

In practice, when it is desired to shift the hanger from its normal toits actuated position, the operator of the construction can so shift thehanger by engaging the base portion 41 and/or the secondary leg portion42 of the upper portion X of the hanger with his fingers.

It is to be noted that the hanger H can be easily and convenientlyassembled by arranging the upper leg portion 40 in axial alignment withthe bearing opening 21, at one side of the body, turn the hanger to anextreme open position and then shifting the leg portion 40 axially intoengagement in said bearing opening and to a position when the plane ofthe hook portion Y occurs in the plane of the slot 30; whereupon thehanger can be rotated to its normal position.

It will be apparent that the hanger, being yieldingly engaged in or withthe body, is not subject to being accidentally disengaged therefrom andlost. Accordingly, my new construction is such that it can beadvantageously assembled and subsequently stored, shipped, handled andotherwise manipulated without the possibility of the body and hangerbecoming disassembled.
